jQuery .on() method not delegating events correctly for dynamically added elements in a complex nested structure
I've been banging my head against this for hours. I'm having trouble getting jQuery's `.on()` method to work correctly with dynamically added elements within a complex nested structure. I am using jQuery version 3.6.0 and relying on event delegation to handle click events on buttons that are added to a list inside a modal. The HTML structure looks something like this: ```html <div class="modal"> <div class="modal-content"> <ul class="item-list"> <li data-id="1">Item 1 <button class="btn-click">Click Me</button></li> <li data-id="2">Item 2 <button class="btn-click">Click Me</button></li> </ul> <button id="add-item">Add Item</button> </div> </div> ``` I set up the event delegation like this: ```javascript $(document).on('click', '.btn-click', function() { const itemId = $(this).closest('li').data('id'); alert('Button clicked for item ID: ' + itemId); }); ``` This works perfectly for the existing list items. However, when I try to add new items using the following code, the event handler does not get triggered for the new buttons: ```javascript $('#add-item').on('click', function() { const newItemId = $('.item-list li').length + 1; $('.item-list').append(`<li data-id="${newItemId}">Item ${newItemId} <button class="btn-click">Click Me</button></li>`); }); ``` I expected the newly added buttons to trigger the same alert when clicked, but they do nothing. I’ve double-checked that the buttons are being added correctly to the DOM, but the click event seems to be unresponsive for these new elements. I've also tried using `.on('click', '.btn-click', ...)` directly on the `.item-list` instead of the `document`, but that didn't work either. Is there something I'm missing about how event delegation works in this case? Any insights would be greatly appreciated! I'm working on a application that needs to handle this.
